>When we created BufferPoolMXBean (in JSR-203) then the goal was to make
it easy to monitor current usage. It wouldn't be hard to track peak
usage if that is important. Direct buffers have not been page aligned
for some time so that is probably not worth trying to expose. The
nio-dev and serviceability-dev would be the right place to being
proposals in this area.
